Description

Technical Field

[0001] The utility model relates to the technical field of decorative covers, and more specifically to a roof decorative cover. Background Art

[0002] At present, due to technological and industrial changes, new energy vehicles have become the backbone of the transformation and upgrading of the automobile industry, and the new energy vehicle industry has also ushered in unprecedented development opportunities. However, how to extend the driving range of new energy vehicles has always attracted much attention in the industry.

[0003] In order to increase the vehicle's range and add a power battery pack, the roof-mounted power battery can maximize the space inside the vehicle. However, roof air conditioning, pantographs and other components can be added, resulting in an uneven and messy top of the vehicle, increasing the wind resistance of the vehicle while driving, and affecting the vehicle's aesthetics and market competitiveness.

[0004] Most of the existing commercial travel car roofs are just a top cover. Because the top cover is just a thin shell, when the vehicle is traveling at high speed or encounters strong winds, the external air flow rate is accelerated, which will form a large air pressure difference on the surface of the roof decorative cover, so that it is easy to deform under the action of the pressure difference and may be opened under the action of such pressure difference, thereby reducing the driving safety and the aesthetics of the vehicle. Therefore, a roof decorative cover is proposed. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a roof decoration cover to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roof decorative cover, including a cover body, a wind guide head is arranged at one end of the cover body, a plurality of diverter plates are evenly arranged on the wind guide head, a plurality of guide plates are arranged on the top of the front end of the cover body, each of the guide plates is respectively connected to the corresponding end of the diverter plate, a tail wing is arranged at the rear end of the cover body, and mounting grooves are symmetrically opened at the bottom end of the cover body.

[0007] It is connected and fixed to the roof through the installation groove. When the vehicle moves, the diverter plate diverts the wind, and with the cooperation of the guide plate, the diverted wind is guided to both sides, reducing the air flow rate on the top of the cover, thereby reducing the air pressure difference, thereby improving the fixity of the cover installation and preventing it from being lifted.

[0008] Preferably, a plurality of mounting holes and fixing holes are respectively provided on both sides of the mounting groove, and each of the mounting holes is respectively matched with a corresponding fixing hole.

[0009] Preferably, a bottom beam is provided at the bottom of the cover body, and the bottom beam is an arc-shaped structure protruding downward.

[0010] Preferably, the side view cross-section of the cover body has an inclined downward structure.

[0011] Preferably, both the tail fin and the air guide head have an arc-shaped structure, and the arc surface angle at the end of the tail fin is smaller than the arc surface angle of the air guide head.

[0012] Preferably, the cross-sectional dimension of the flow guide plate gradually decreases from the end connected to the flow splitting plate to the other end of the flow guide plate.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. It is fixedly connected to the vehicle roof through the installation groove. When the vehicle is moving, the flow splitting plate splits the wind, and with the cooperation of the flow guide plate, the split wind is guided to both sides, reducing the air flow velocity at the top of the cover body, thereby reducing the air pressure difference. In this way, the fixing of the cover body installation is improved, and it is avoided from being lifted, thus improving the driving safety of the vehicle.

[0015] 2. By passing the stud through the installation hole and connecting it to the fixing hole through the structure of the vehicle roof inserted in the installation groove, the decorative cover can be installed and fixed, and the installation is convenient and fast.

[0016] 3. When there is a large air flow at the top of the cover body and a pressure difference is generated between the inside of the vehicle during high-speed driving of the vehicle, the cover body is subjected to an upward pressure, and the bottom beam can improve the support for the pressure, thereby avoiding deformation of the decorative cover and improving safety and aesthetics.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the Figures 1-4 roof decoration cover, which includes a cover body 1. One end of the cover body 1 is provided with a wind guiding head 2, and a plurality of flow dividing plates 3 are evenly arranged on the wind guiding head 2. A plurality of flow guiding plates 4 are arranged at the top of the front end of the cover body 1, and each flow guiding plate 4 is respectively connected to the end of the corresponding flow dividing plate 3. A tail wing 5 is arranged at the rear end of the cover body 1, and mounting grooves 9 are symmetrically opened at the bottom end of the cover body 1.

[0024] During specific implementation, it is connected and fixed to the roof through the mounting grooves 9. When the vehicle is moving, the flow dividing plates 3 divide the wind, and under the cooperation of the flow guiding plates 4, the divided wind directions are guided to both sides, reducing the air flow rate at the top of the cover body 1, thereby reducing the air pressure difference. In this way, the fixing of the cover body 1 is improved, and it is prevented from being lifted.

[0025] A plurality of mounting holes 6 and fixing holes 8 are respectively opened on both sides of the mounting groove 9, and each mounting hole 6 is arranged in cooperation with the corresponding fixing hole 8.

[0026] During specific implementation, the decorative cover can be installed and fixed by passing a stud through the mounting hole 6 and connecting it to the fixing hole 8 with the structure of the roof inserted into the mounting groove 9. The installation is convenient and fast.

[0027] A bottom beam 7 is arranged at the bottom of the cover body 1, and the bottom beam 7 is an arc-shaped structure protruding downward.

[0028] During specific implementation, when the air flow at the top of the cover body 1 is large and a pressure difference is generated with the interior of the vehicle, the cover body 1 is subjected to an upward pressure, and the bottom beam 7 can improve the support for the pressure, thereby preventing the decorative cover from deforming and improving safety and aesthetics.

[0029] The side view cross-section of the cover body 1 is an inclined downward structure, so that during rainy weather, rainwater can flow backward along the cover body 1, avoiding blocking the front side of the vehicle and improving driving safety.

[0030] Both the tail wing 5 and the wind guiding head 2 are arc-shaped structures, and the arc surface angle of the tail wing end 5 is smaller than the arc surface angle of the wind guiding head 2. With the arc-shaped structure of the tail wing 5, during the vehicle's driving process, rainwater can flow out along the tangent direction of the arc surface, thereby reducing the amount of rainwater flowing vertically downward.

[0031] The cross-sectional dimension of the deflector 4 gradually decreases from the end connected to the splitter plate 3 to the other end of the deflector 4, so as to enable the split air flow to blow obliquely backward from the housing 1, further reducing the air volume flowing through the surface of the housing 1, thereby further reducing the pressure difference.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
